The effect on blood pressure of a monophasic oral contraceptive containing ethinylestradiol and gestodene

To obtain an overview of the effect of monophasic gestodene on blood pressure and to determine the frequency of “OC elevated BP/hypertension,” the results of blood pressure monitoring from four clinical studies of contraceptive efficacy and safety have been retrospectively analyzed. A total of 1930 women took part in the studies, which recorded BP for up to 24 cycles. Analysis of results revealed that 97 women (5.0%) showed an increase in blood pressure from previously normal to elevated values while taking monophasic gestodene, with only 26 (1.35%) fulfilling the criteria of “OC elevated BP/hypertension.” Only four women dropped out of the trials due to hypertensive blood pressure values, while 67 women (3.5%) experienced a normalization of previously elevated blood pressure measurements. In conclusion, this analysis has confirmed that gestodene has a negligible effect on blood pressure, with increased BP a relatively rare event.
